Be itzknown thatI,\DAv1D HALL RICE, of

Lowell, in the county of Middlesex and Corn` kmonwealth of Massachusetts, have invented certain Improvements'in Ring-Spinning, Thros- Rtle, and'other. Spinning-Frames, of which the following'is aspecilication:

`My`invention relates, first, to the combina-` tionof a compound `live spindle, partly ho1.

low and partly solid, with a dead or stationary y spindle, in the manner hereinafter described, H so as tosecurethe greatest possible strength `and lightness in the live` spindle `with the smallest bearings, as wellas perfect steadi-V i ness of the dead spindle; second, to combin- .ing withthe upper bearing of the live spindle an automatic (lubricating arrangement, such as hereinafter described, having its'oil-cham- #ber Ain ,the upperl part of the -dead spindle, qwherebyithe upper` bearing of thelive spindlev `is automatically lubricated; third, to forming' a the lowerbearing of thelive spindleofa separate piece of metal o r 'ring and driving it on thelivespindle,and alsol toforming the up:

per bearingst'epof.aseparate piece of metal driven into its socket, bothbeing removable without injury to the live and dead spindles,

theobject being lto remove the lower bearing and thc upper bearing step whenlworn out thread upon either endof the bobbin and'spindle, as hereinafter described; ,fth, to placing inthe lower oil-reservoir a horizontal plate of considerable thickness, having a central hole y in it, in which the lower end of the live spindle rotates without touching the plate, the object being to prevent' the spindle from throwing the oil away from the lower bearing, or even out of theV reservoir.

placed so as to leave a space between it and t the bottom of thereservoir, and has holes through it, around the central hole through Said plate is which the oil flows tothe lower bearing of the live spindle.

Figure lis an elevation of a spindle embody- 'ing my invention. Fig. 2 is an enlarged vertical sect-ion of the material parts of the same. Fig. 3 is an end view of the spindle from above, showingthe operation of the adjustable latch. l Y

.Duplex spindles have hitherto `been con structed with the dead spindle extending to the top, or nearly to the top of the live spindle within it. This has rendered it necessary to make the dead spindle so largelin order to support the upper 'bearing ofthe live spindle steadily, that the lowerv bearing ofthe live spindle, which must necessarily be on the circumference of the lower part of the dead spindle, was also-,very large, causing great friction and loss. of lpower in running at high speed. The live spindle had also toV be constructed correspondingly larger and heavier to possess ,the requisite strength. Great difficulty has alsobeen .experienced in keeping the upper bearingof the` live spindle properly lubricated from its inaccessible position within the, top

-of the spindle when adjusted. Tcobviate these difficulties 'I construct the dead spindle d3, which is driven rmly into the bolster of the lower oil-reservoir, of but about one-halt the usual length, so that it will carry the upper bearing of the live spindle about the middle of the latter. Being, short it can be made much Smaller and carry the upper bearing steadily,

while the lower bearing is reduced in size. P

isa section of the rail of a spinning-frame, in

which the bolster and lower oil-reservoirare secured by a nut or set-screw. The live spindle D E is constructed `of the hollow part D,Acov

. ering and' running outside of the dead spindle andthe solid part E resting inthe top of and above `the latter.

and has formed on its interior circumference the lower bearing of the spindle. This bearing should be below the level of the oil in the lower oil-chamber. On its exterior circum- .ference the ring e is turned to correspond with the hole through the plate When the ring is revolving with the spindle this rricn.

These parts are secured firmly together with their axes in a right line.

form and relation of itselil and the plate t keep the oil from being thrown out of the lower chamber by the rotation of the spindle. The ring e and plate i should not touch each other, a small space being left between them. The plate t' is secured in the sides of the oilrcservoir in a horizontal plane a short distance above the bottom of the oil-reservoir, and holes n ln, are made through it to allow the oil to circulate above and below it. M is a passageway made through the shoulder of the live spindle, between its parts D and E, to allow the oil to be supplied to the upper bearing, when necessary, and oil-chamber in the dead spindle. h is the whorl by means of which the live spindle is driven in the usual manner. On the lower end of the part E of the live spindle is formedthe upper bearing, resting in the step af. This bearingis made tapering upward from its lower end, and the step a and itself fitted to each other.' The step is made of any suitable metal, and driven into a chamber in the top of the dead spindle. Passage-ways o o extend from the bottom point at which the bearing rests in the step and through the step on each side of the bearing perpendicularly to the oil-chamber d beneath it, and within the dead spindle. This combination of the upper bearing thus formed with the step a, oil pissageways o o, and oil-chamber d forms au automatic lubricating device, by which the revolution of the spindle will draw the oil up from the chamber through the central passageway o upon the bearing, and any surplus oil brought to the top of the step will ilow down to the chamber again through the outer passage-ways o o. The spindle may thus be run a month at a time without reoiling the upper bearing. S is an adjustable latch, supported at one end by and pivoted upon the standard j' secured to the side of the lower oil-reservoir,A

so that it can swing in a horizontal plane. The other end of the latch is passed through a horizontal slot in the plate g, which is seY cured upon the other side of the reservoir. As the latch S is circular in form, when it is drawn back the live spindle may be removed from the dead spindle in the usual manner 5 but when the latch is pushed forward to the other eX- tremity of the slot it passes just above the whorl and prevents the live spindle being raised from its position when the bobbin is being removed from it.

In addition to the advantages before enumerated of placing the upper bearing of the live spindle D E within it, about midway between its upper end and the rail P, and causing it to rest in the top of the dead spindle B,

I have found that the drag or draft of the thread or yarn, while being spun upon the live spindle at either its upper or lower end, drawing the spindle to one side, and causing it to run unsteadily on ordinary spindles, is, by the described arrangement of the upper bearing, resisted and overcome by the rotary motion of the opposite end ofthe live spindle acting against the upper bearing as afulcrum, and the spindle runs steadily.

The live spindle D E is designed and fitted to pass nearly through the bobbin which carries and spins the thread, and the upper bearing of the spindle is, therefore, by this yarrangement, brought near Vthe center of the bobbin longitudinally, the top of the latter being but about one-eighth of an inch above the top of the spindle. Should the bobbin be made to come higher above the top of the spindle the upper bearing of the latter should be proportionally changed upward, my object being to keep this bearing near the longitudinal center of the bobbin which carries the weight of thread upon the Spindle.

What I claim as new and my invention is 1. The compound spindle, composed of the parts B D E, constructed and combined substantially as described.

2. The upper bearing of the live spindle D E, in combination with the step a, passageways o o, and oil-chamber dplaced in the top of the dead-spindle B, substantially as described. i

3. The removable ring or bearing e, combined with the lower end of the live spindle D E, and forming its-lower bearing, substantially as described.

4. The removable bearingstep a, combined with the top of the dead spindle B, and forming the support or socketof the upper spindlebearing, substantially as described.

5. The live spindle D E, having its upper bearing, which rests at the top ot' the dead spindle B, placed within it at or near a point equidistant from its upper and lower ends, substantially as described.

6. The horizontal plate i, provided with a central hole, in which the spindle revolves, and having other outside holes n n, placed within and above the bottom of the lower oilchaxnber, and in relation to and in combination with the lower end of the live spindle D E, substantially as and for the purposes described.
